#Bills HC Rex Ryan on ESPN Radio: There's no way Rob is the more handsome brother.

On Tuesday, Alex Marvez of Fox Sports reported defensive coordinator Dennis Thurman is "expected to work more with [defensive backs] now while Rex/Rob run the defense."

The New Orleans Saints fired Rob Ryan in November after he served as the team's defensive coordinator for two-plus seasons. Under Ryan, the Saints defense sank to the bottom of the league in 2015, giving up the most points per game on the season (29.8).

Rob and Rex Ryan last coached together from 1994 to 1995 under their father, Buddy Ryan, with the Arizona Cardinals, where Rob oversaw defensive backs and Rex coached the defensive line and linebackers.

Rex Ryan's Bills finished 8-8 on the season, and although they missed the playoffs, they prevented the Jets from making it with a 22-17 win in Week 17. Still, Rex hasn't reached the postseason since the 2010 season.
